makVrv::DtGpuCulling Class Reference

This class is a component of the DtIndirectGeometry It inputs are: -> the instances registered with DtIndirectGeometry -> the viewing parameters (view matrix, projection matrix, etc) -> the indirect registrar (so that it can generate gpu data for -> the models of the instances from the interim data accessible -> via the registrar It outputs are: -> Tndirect command buffer -> The count of the indirect commands -> The input instances shuffled around/culled/lod'ed reflecting -> their order within the indirect command buffer generated -> It will also (optionally) do culling and lod.

virtual void makVrv::DtGpuCulling::updateGpuBuffers ( osg::RenderInfo &  renderInfo )

virtual

updateGpuBuffers outInstanceTransformsUpdated indicates whether instance transforms that were marked dirty were sent to the GPU. This may not always happen with a call to updateGpuBuffers.

virtual void makVrv::DtGpuCulling::modelIdsToNumInstancesChanged ( void  )

virtual

indicate to the culling that model ids to num instances changed so that internal maps get updated

virtual void makVrv::DtGpuCulling::updatePerInstancePerGeomBuffers ( const MapIntToInt &  modelIdsToNumInstances, const osg::Camera *  camera  )

virtual

update the buffers that are needed to be correct every frame

virtual void makVrv::DtGpuCulling::doCulling ( const DtIndirectViewParameters &  viewParameters, const osg::FrameStamp *  frameStamp, const DtGlBuffer *  gpuLodVisibleBuffer, const DtGlBuffer *  gpuDofTransformBuffer, const DtGlBuffer *  gpuSwitchStateBuffer, const DtGlBuffer *  gpuPerInstanceDataBuffer, const osg::Camera *  camera, bool &  outputInstanceBufferChanged  )

virtual

Do the culling (view frustum, lod, switch)

Parameters

outputInstanceBufferChanged

indicates whether output instance buffers that get get bound were determined to need resize and were resized, and because of that the gpu address also likely changed (which should trigger an external re-generation of the vao which uses these)

For bindless, bind the output buffers from the culling with buffer address range This is because in bindless, the main buffers are via indirect bindless call (which is internally a buffer address range bind).
